` Application mea september 1s, 1922. serial No. 588,640.

lo all 'whom it may concern.' .v Be it known that ALFRED BRANN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, has invented certaln new. and useful Improvements in Violins, of which the lfollowing is a specification. 4

This invention relates to lmprovements 1n violins.

An vobject of the invention is to .improve the vtoney of the violin by making the neck the hollowportion communi- :eating with the interior of the body and providing a, valve on the under side of the neck adjacent the outer end thereof, ada ted for opening and closing an opening 1n t e neck, so that the sound passing therethrough may be varied. p

Another object of the invention 1s to use a hollow sounding post in the violln.

In the drawings:

Fig. 1 indicates a sectional .view through a violin, showing the application of the 1nvention.

Fig. 2 is a bottom tion of the violin. A

1 indicates the body of a violin having a neck 2 and strings 3v secured to the end of the body assin over the bridge 4 and se- `cured to t e nec portion in the usual manner. e The neck of the violin is the same shape as ordinarily used but is formed tubular or hollow as indicated at 5 for the greater portion of its length, the inner end projecting into the body being open and in-communicatlon w1tl1 the interior thereof, and the outer end having an opening 6 formed on the bottom side thereof. A valve 7 is pivotally mounted on the neck as indicated at8 and is adapted to view of the neck porclose the opening 6 in the neck, so that sound coming through the neck from the' body is permitted to ass out through the opening or prevented t erefrom by closing the valve, which can be easily operated by the hand of the player, which grasps the neck portion. As the neck portion of the violin is considerably weakened by making ithollow as indicated, it is found necessary to use means for reinforcing the neck to prevent it from splitting or breakin and thus impairing the use of the instrument. The inside of the neck portion is coated with a mixture of ground lass and glue forming a thin film 11 aIong the entire interior of the hollow out portion of the neck. This film substantial y reinforces the neck and at the same time is sufiiciently resilient so as not to interfere with the sound qualities of the instrument.

To further im rove the tone of the instrument, the soun ing post 9 is formed of a tubular member having an opening 10 intermediate the end portions thereof.

In laying the instrument, the sound will 05 pass rom the body through the hollow neck portion and the p ayer can open or close the valve for varying t e sound effect from vthe 'y instrument.

What I claim is:

A violin having a body portion and a neck portion, that part of the neck underlying the strings being of hollow formation and fully open to the interior of the body, thev under portion of the neck beyond the body being formed with a valve controlled outlet communicating with the hollow portion.

' In testimony whereof I afiix my signature.
